Power outages are a way of life here. Here is the current schedule for the Kantipur Temple House. You can see it is supplemented by generator hours which only address a secondary system of lights, no plugs or hot water. And think what the mass use of generators does for pollution.
I don’t know all the reasons, but less than ideal monsoon and snow conditions and corruption and strife leading to under investment in power production infrastructure are key ones. You also have to wonder about distribution when you see wiring like this, and this is not the worst we have seen, this is just close by. Notice the birds nest.
Here is a view of the pile of propane tanks it takes just to keep this one small hotel set with generator power.
